Abstract

The invention relates to a low-energy-consumption counterflow closed cooling tower. The cooling tower comprises a cooling tower shell and a draught fan mounted on the top of the cooling tower shell. The cooling tower shell is internally provided with a water cooling heat exchange tube bundle. A piece of packing is arranged above the water cooling heat exchange tube bundle. Spray heads for sprayingcooling water are arranged above the packing. First air inlet windows are formed in the positions, between the water cooling heat exchange tube bundle and the packing, of the cooling tower shell. Thelow-energy-consumption counterflow closed cooling tower has the beneficial effects that cooling water is subjected to air cooling through the packing, and energy consumption can be remarkably reduced; the water cooling heat exchange tube bundle is arranged on the lower portion of the cooling tower, the height of the water cooling heat exchange tube bundle is lowered, and the cooling tower is convenient to maintain and operate; and the air cooling heat exchange tube bundle above the spray heads facilitates elimination of white mist.

Description

technical field [0001] The invention belongs to a cooling device, in particular to a low energy consumption counter-flow closed cooling tower. Background technique [0002] At present, closed cooling towers can be divided into counterflow type (fengshui in different directions), downstream type (fengshui in the same direction), and crossflow type (fengshui vertical crossing) according to the flow direction of wind and water outside the tube. Among them, the counterflow type has many advantages, such as high cooling efficiency, small footprint, and convenient layout, so it is widely used. However, the wind resistance of the counterflow cooling tower is relatively large, and the energy consumption is large. In addition, the cooling tower will produce white fog under certain meteorological conditions, which will have an adverse impact on the environment. Contents of the invention [0003] The purpose of the present invention is to propose a technical scheme of a low-energy ...
